Subject: [RFC 00/16] xen/arm: Introduce alternative runtime patching for ARM64
Date: Thu, 5 May 2016 17:34:09 +0100 [thread overview]
Message-ID: <1462466065-30212-1-git-send-email-julien.grall@arm.com> (raw)
Hello,
Some of the processor erratum will require to modify code sequence. As those
modifications may impact the performance, they should only be enabled on
affected cores. Furthermore, Xen may also want to take advantage of new
hardware features coming up with v8.1 and v8.2.
The first part of the series adds the alternative infrastructure, most of the
code is based on Linux v4.6-rc3. The rest of the series implements errata
for Cortex-A57 and Cortex-A53.
Yours sincerely,
Julien Grall (16):
xen/arm: Makefile: Sort the entries alphabetically
xen/arm: Include the header asm-arm/system.h in asm-arm/page.h
xen/arm: Add macros to handle the MIDR
xen/arm: arm64: Import flush_icache_range from Linux v4.6-rc3
xen/arm: Add cpu_hwcap bitmap
xen/arm64: Add an helper to invalidate all instruction caches
xen/arm: arm64: Move the define BRK_BUG_FRAME into a separate header
xen/arm: arm64: Reserve a brk immediate to fault on purpose
xen/arm: arm64: Add helpers to decode and encode branch instructions
xen/arm: Introduce alternative runtime patching
xen/arm: Detect silicon revision and set cap bits accordingly
xen/arm: Document the errata implemented in Xen
xen/arm: arm64: Add Cortex-A53 cache errata workaround
xen/arm: arm64: Add cortex-A57 erratum 832075 workaround
xen/arm: traps: Don't inject a fault if the translation VA -> IPA
fails
xen/arm: arm64: Document Cortex-A57 erratum 834220
